DESCRIPTION
The P89C51RA2/RB2/RC2/RD2xx contains a non-volatile
8KB/16KB/32KB/64KB Flash program memory that is both parallel
programmable and serial In-System and In-Application
Programmable. In-System Programming (ISP) allows the user to
download new code while the microcontroller sits in the application.
In-Application Programming (IAP) means that the microcontroller
fetches new program code and reprograms itself while in the
system. This allows for remote programming over a modem link.
A default serial loader (boot loader) program in ROM allows serial
In-System programming of the Flash memory via the UART without
the need for a loader in the Flash code. For In-Application
Programming, the user program erases and reprograms the Flash
memory by use of standard routines contained in ROM.
The device supports 6-clock/12-clock mode selection by
programming a Flash bit using parallel programming or
In-System Programming. In addition, an SFR bit (X2) in the clock
control register (CKCON) also selects between 6-clock/12-clock
mode.
Additionally, when in 6-clock mode, peripherals may use either 6
clocks per machine cycle or 12 clocks per machine cycle. This
choice is available individually for each peripheral and is selected by
bits in the CKCON register.
This device is a Single-Chip 8-Bit Microcontroller manufactured in an
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The instruction set is 100% compatible with
the 80C51 instruction set.
The device also has four 8-bit I/O ports, three 16-bit timer/event
counters, a multi-source, four-priority-level, nested interrupt structure,
an enhanced UART and on-chip oscillator and timing circuits.
The added features of the P89C51RA2/RB2/RC2/RD2xx make it a
powerful microcontroller for applications that require pulse width
modulation, high-speed I/O and up/down counting capabilities such
as motor control.
